Hello RaiC, i have a ROCKCHIP MP4, precisely a RK2606 based player with screen touch, cam, 2gb of internal memory and SD slot.
Is like the image you post and knob URL.
This firmware belongs to my ROCKCHIP MP4 and work excelent (i did the firmware upgrade with Rockchip_Consumer_Firmware_Update_v3.1.2.0 )
DCT+HTC-039+MV339+9325+照像.rar
i have some advices:
- rename the firmware file, to avoid the update tool fail, for example rename to: "DCT.rfw".
- before of all go to the recovery guide
- use a soft like ChipGenius to retrieve your CHIP MODEL (if u cant open your mp4 device).
GOOD LUCK!
